>The later might make some sense, though, as part of training for the drone operators. Spotting a small disturbance in the surface of a street such as a pothole could require similar skills to spotting a small disturbance in the surface of a street due to someone having buried a timed or remote-control explosive there. Okay never thought of that situation, it would be a good training scenario.
